红坑口于1958年开坑.现已下掘到-527m 中段,井深816m,已开拓了16个中段,其中:平窿3个,竖井开拓13个中段。通过20多年的生产,已结乘了8个中段,正在作业的7个中段,为了接续好生产,深部盲井已施工。红坑口围岩稳固,无明显地压影响。采矿方法的选择关系到整个生产衔接,均衡生产,关系着整个矿山的经济效益。本文拟列现有采矿方法从技术、经济、生产、管理上进行论证,提出近期不同采矿方法比例,供商定。
Hongkengkou opened a pit in 1958. It has now been excavated to the middle of -527m with a well depth of 816m and has opened up 16 middle sections, of which 3 are open holes and 13 are open shafts. After more than 20 years of production, it has taken 8 middle sections and is operating in the middle of the 7 sections. In order to continue the production, deep blind wells have been constructed. Hong Hang mouth surrounding rock solid, no significant pressure. The choice of mining method is related to the convergence of the entire production, balanced production, the economic benefits of the entire mine. This paper plans to list the existing mining methods from the technical, economic, production and management demonstration, put forward the proportion of different mining methods for the recent agreement.
